Porous PE Filters are manufactured from sintered polyethylene material with a controlled porous structure, offering reliable filtration, venting, and flow control performance in a lightweight and corrosion-resistant form. These filters are widely used for air, gas, and liquid applications where chemical resistance and stable permeability are required.

They provide low pressure drop, good particle retention, and excellent resistance to moisture and many chemicals. Porous PE filters are commonly supplied as discs, tubes, rods, sheets, caps, and custom molded components.

Typical applications include air vents, water filtration, battery venting, medical devices, automotive reservoirs, chemical equipment, mufflers, and protective vents for electronic enclosures.

CMI Filtration can manufacture Porous PE Filters in various micron ratings, sizes, and custom designs based on customer drawings or samples.
